Question

1.You have three hypothetical (please note, these are not REAL) elements, X, Y, and Z, with the following electronegativity values:

X = 0.6

Y = 3.2

Z = 3.5

Please note that X, Y, Z are only placeholders and aren’t referring to an actual specific element on the periodic table.

You react the hypothetical elements to form the hypothetical substances XY, XZ, and YZ.

Answer the following questions:

● What kind of substance is XY? What kinds of bond is it? Explain your answer.

● What kind of substance is XZ? What kinds of bond is it? Explain your answer.

● What kind of substance is YZ? What kinds of bond is it? Explain your answer.

● For any ionic compounds, which element is the cation (meow) and which is the anion?

Answer 1

A)

XY = 3.2-0.6 = 2.6, this is most likely a salt, ionic compound,

it bonds via elecotrstatic (ionic) bonds.

this is mainly because of the difference of electronegative, the electorn of X i s donated to Y

b)

XZ = 3.5-0.6 = 2.9

it bonds via elecotrstatic (ionic) bonds.

this is mainly because of the difference of electronegative, the electorn of X i s donated to Y

c)

YZ --> 3.5-3.2 = 0.03

this must be nonpolar molecule, sinc eit has low electornegativity diffference

the electrons are shared almos equally, if not equal.

a)

for the ionic compound, the most electronegative --> anion, Y

the leaset electronegative --> metal --> caiton --> X
